One-time criminal Vince (Harris) turned his life around when he fell in love with Sandy (Union). Nearly 20 years later, the still-happy couple are looking forward to spending a quiet New Year's Eve in their country home with their good-natured son, DJ (Miles J. Harvey). Then Vince's other son, Rocco (Lewis Pullman), shows up unannounced with his pregnant girlfriend, Marina (Emanuela Postacchini), and Vince's first wife, Ruth (Coolidge), in tow. It is not a happy reunion. Ruth is rude, lewd, and randy, while Rocco - who never divested himself of the family business - is clearly hiding something sinister. Hot on Rocco's tail is Lefty (Bill Murray), an aging mafioso with a score to settle regarding his own son. When Lefty catches up with Vince's teeming clan, it seems likely that blood ties will yield blood spilled.
